Risk of thromboembolism with thrombopoietin receptor agonists in adult patients with thrombocytopenia: systematic review and meta-analysis of randomi…
2012
Background and objective: Thrombopoietin receptor (TPOr) agonists (romiplostim and eltrombopag) are a new approach for the treatment of thrombocytopenia-associated conditions. They promote megakaryocyte differentiation, proliferation and platelet production. In the European Union, both are orphan drugs with an indication restricted to splenectomized immune thrombocytopenic purpura patients who are refractory to other treatments. Due to increasing platelet counts, these drugs may represent a risk for thromboembolic complications. We analyzed whether TPOr agonists affect thromboembolisms occurrence in adult thrombocytopenic patients. Materials and methods: We conducted a systematic review and…
A natural-like synthetic small molecule impairs bcr-abl signaling cascades and induces megakaryocyte differentiation in erythroleukemia cells
2013
Over the past years, we synthesized a series of new molecules that are hybrids of spirocyclic ketones as complexity-bearing cores with bi- and ter-phenyls as privileged fragments. Some of these newly-shaped small molecules showed antiproliferative, pro-apoptotic and differentiating activity in leukemia cell lines. In the present study, to investigate more in depth the mechanisms of action of these molecules, the protein expression profiles of K562 cells treated with or without the compounds IND_S1, MEL_T1, IND_S7 and MEL_S3 were analyzed using two-dimensional gel electrophoresis coupled with mass spectrometry. Proteome comparisons revealed several differentially expressed proteins, mainly r…
